Windows Host Process RUNDLL32

To load and execute 32-bit DLL files, Windows provides the Rundll32 program. Files of this type contain both data and code, and are frequently shared between different Windows applications.

It can be challenging to determine what caused a notification to appear on one of your workplace computers stating that Rundll32 has ceased operating. There may be an issue with the Rundll32 tool, a faulty DLL, or the program that is trying to use the DLL.

Sometimes, malicious software that attempts to disguise itself as a legitimate Windows process would use a filename that is identical to that of a legitimate system utility, such as the Rundll32 utility.

What is Host Process RUNDLL32

The Windows DLL (dynamic linked library) file launcher, rundll32.exe, is an essential component of Microsoft Windows. For instance, if you’re running a Windows app that requires a DLL, you can use rundll32.exe to make that DLL available to your program.

If you disable rundll32.exe, it’s probable that many features of Windows and many Windows programs won’t work since a Windows DLL library contains code that can be used by more than one program on Windows at the same time.

Why does rundll32.exe Access the Network?

From Austin, Texas, USA, we were able to determine that rundll32.exe communicates with a server that appears to be under Microsoft Corporation’s control via the GlassWire application.

There was no other.exe-related network activity that we could find. We think rundll32.exe communicates with settingsfd-geo.trafficmanager.net. So that you can control how data is sent and received from each of your computer’s clients.

It appears that your DNS server is doing this traffic control so that your computer and programs may function normally.
